Answer:
C
Step-by-step explanation:
- 6(2x + 3) - 4(5x + 2)
- 12x + 18 - 20x -8
- -8x +10
3x = 5(x-4)
I am not sure about the equal sign though.

Step-by-step explanation:
If the triangle is right then the square of the longest side (hypotenuse) will equal the sum of the squares of the other 2 sides.
longest side is x² + 1, then
(x² + 1)² =
+ 2x² + 1
The sum of the square of the other 2 sides
(x² - 1)² + (2x)²
=
- 2x² + 1 + 4x² =
+ 2x² + 1
Hence triangle is right
I agree with the person above.
The sum of negative eighteen and a number is eleven:
-18 + x = 11 which is the same as A. x - 18 = 11; x = 11 + 18; x = 29
